Python Ensurepip Module
The ensurepip module provides support for bootstrapping the pip installer into an existing Python installation or virtual environment. This bootstrapping approach reflects the fact that pip is an independent project with its own release cycle, and the latest available stable version is bundled with maintenance and regular releases of the CPython interpreter.
